Title pretty much explains it, how did a desynch in pvp ruin your game? What did it do?
Something that happened to me was the opponent had a bonewall out and all was going well untill the desynch spammed 5 0/0 creatures. This is maybe a common desynch type but the death effects where triggered and the opponent got a 17 hit bonewall for my lone OE to hack away at. The weird thing is though, with all my desynchs, it always has the icon up top. This one didn't :O
